Bonnet Assembly Options

Optimize your BOP with greater certainty and a smaller footprint

Further optimize Cameron BOPs with bonnet assemblies designed specifically for our equipment.

Bonnet options employ more closing force in a simplified design, offering greater certainty and a smaller footprint.

A BOP equipped with standard bonnets is configured to deliver enough closing force to seal a well with nonshearing rams, such as fixed-bore pipe rams, variable-bore rams (VBRs), FLEXPACKER ram technology, or FLEXPACKER-NR narrow-range ram technology. For some applications, shearing bonnets are required.
